Geek Challenge: New Year's Beeramid by the Numbers

Geek Challenge: New Year's Beeramid by the Numbers

During a New Year's Eve party, a simple pyramid was constructed by standing 3 beer cans on a table in a triangle, and then placing a single can on the top center of the three. The pyramid was expanded by expanding the triangular base to 3 cans on each side, adding 2 more cans to the second layer and adding a single can on top as the third layer.

How many cans are in the pyramid when it is expanded to 8 layers?

A. 70
B. 85
C. 120
D. 256

Extra credit:  How many cans would be in a 100 layer pyramid?

The correct answer with the best engineering content will be this month’s winner. Submit your responses to: geekchallenge@dmcinfo.com
